Bare Single-Mode G652D/G657/G654 Bend-Optimized Low Loss Optical Fiber Product Description Low Loss Single-mode Fiber • Designed for operation over the fuerll optical spectrum from 1260-1625 nm, and hence the transmission capacity is increased • Much lower attenuation over the full optical spectrum from 1260 nm to 1625 nm, which meet the demand of extended long distance transmission • Outstanding optical performance supporting high-speed transmission technologies such as DWDM and CWDM • Being compatible with existing 1310 nm equipment • Good protection and excellent strip force stability • Accurate geometrical parameters that insure low splicing loss and high splicing efficiency Thanks to its broad usable optical spectrum and outstanding attenuation performance, FullBand® Plus Low Loss Single-mode Fibre is the optimum choice that supports various applications such as Ethernet, Internet Protocol (IP), Asychronous Transfer Mode (ATM), Synchronous Distribution Network (SDH) and Wavelength Division Multiplexing (WDM). FullBand® Plus Low Loss Singlemode Fibre provides wider bandwidth and much lower signal attenuation for backbone, metropolitan area and access networks.
